The promoter: A) Is an RNA sequence necessary for activating the transcription of a gene B) Is an RNA sequence necessary for activating translation C) Is a DNA sequence necessary for regulating the transcription of a gene D) Is the site of initiation of gene transcription E) Is a protein factor necessary for activating gene transcription

Which of the following best describes a promoter?Group of answer choicesA regulatory protein that accelerates mRNA turnoverAn element that promotes termination of transcriptionAn extracellular inducer that controls gene expressionA DNA sequence to which RNA polymerase may bind

A promoter is a part of a protein that controls the protein’s function. a part of a chromosome that can turn a gene on or off. a part of a mRNA that controls its movement to the cytoplasm. a part of a chromosome that increases DNA replication.

What protein is necessary for the binding of RNA polymerase to a gene promoter in bacteria? Histone H3 Histone acetylase DNA telomerase DNA polymerase Sigma factor

What is needed for DNA polymerase to synthesize DNA that is not required for RNA polymerase to synthesize RNA? A fragment of double-stranded DNA usually formed by the binding of a primer A piece of double stranded RNA A promoter or cis regulatory sequence A general transcription factor A gene specific transcription regulator
